On Centos 7.5 base install, there are no utility’s installed by default. So when I tried to mount an NFS share I got this error :

 

  • mount: wrong fs type, bad option, bad superblock on svennd.be:/data,
  • missing codepage or helper program, or other error
  • (for several filesystems (e.g. nfs, cifs) you might
  • need a /sbin/mount.<type> helper program)
  • In some cases useful info is found in syslog – try
  • dmesg | tail or so.

This clearly tells us it cannot communicate with the NFS share, fixing can be done installing : nfs-utils for Centos.

  • yum install nfs-utils

for Debian variants (Mint, Ubuntu, …) this would be :

  • apt install nfs-common

After that, I see happy shares
